b. What is the equilibrium price and quantity in this market?
c. Graph the supply and demand curves for these equations.
d. Suppose the price is $8. What is the new Qs and Qd? What type of disequilibrium situation exists, and what is its magnitude? Briefly describe what will happen to bring the market back to equilibrium.
